First this wren is not sprawling in the same manner that is associated with
the four wing sprawl hypothesis, where the femur would rotate forward and
up/out. In fact the femur as well as the tibia occupy near normal positions,
the knee is probably directed a little inward from its normal position so
that the ankle is oriented as far out ward as possible. Secondly I think
there may be a bit of an optical allusion at play here, making the right
ankle appear closer to the lens than it really is.
